在灾害管理中，减灾和备灾阶段在减少特定灾害造成的损失方面发挥着至关重要的作用。开发模拟防灾减灾活动的信息系统需要整合来自不同多样化数据源的大量数据。我们的工作目标是提供一种有效的方法，通过链接开放数据(LOD)技术，将这些不同的、分布式的数据源转换为标准化的、可交换的通用数据格式，从而实现它们的互操作性和集成性。我们描述了如何在资源描述框架(RDF)中发布不同的数据源集合，LOD的基本数据结构，以及如何将它们与LOD云中的其他数据源互联。通过这些相互关联的RDF数据，萨哈纳灾害管理系统得到了加强，从而形成了一个称为萨哈纳亚洲的系统。萨哈纳亚洲可以模拟减灾和备灾活动，使易受影响的人、应急管理小组以及参与灾害管理的其他组织受益。具有灾害管理背景的参与者对该系统进行了评估，发现它在系统质量、信息质量和整体系统性能方面是有效的。还提出了该系统未来的几个扩展。这些扩展可以很容易地实现，因为它们都以RDF统一表示它们的数据和信息。
In disaster management, disaster mitigation and preparedness phases play vital roles to diminish the damages caused by a particular disaster. The development of information systems which simulate disaster preparedness and mitigation activities requires integration of large amount of data from different diversified data sources. The goal of our work is to provide an effective way, by means of the Linked Open Data (LOD) technology, to bring such different, distributed data sources into a standardized and exchangeable common data format and hence to enable their interoperability and integration. We describe how to publish different sets of data sources in Resource Description Framework (RDF), the basic data structure of LOD, and how to interconnect them with other sources in the LOD cloud. The Sahana disaster management system has been enhanced with these interconnected RDF data leading to a system called Sahana Asia. Sahana Asia can simulate disaster mitigation and preparedness activities, benefiting vulnerable people, emergency management teams as well as other organizations involved in disaster management. It has been evaluated by participants with some backgrounds in disaster management and found to be effective in terms of system quality, information quality and overall system performance. A few future extensions of the system have also been presented. These extensions can be readily implemented as they all uniformly represent their data and information in RDF.
